Underground's HR and Ops Support teams came together for an early morning audiobook listening session featuring Extreme Ownership: How U.S. Navy SEALs Lead and Win. 🎖️ For this listening party, we focused on Chapter 5: “Cover and Move," which parallels Navy SEAL operations and collaboration between business units under one parent organization. The end chapter discussion was a great reminder of how aligned teamwork, shared objectives, and mutual support drive real business success. Here’s to moving in the same direction, as one team in 2026! 💪 #UCCo #WeAreQuanta #ExtremeOwnership #NavySEALs
